"Take nothing on its looks; take everything on evidence. There's no better rule.""Captain, the logical course of action in this situation is to let the inhabitants of Pupolon fend for themselves. We need the device keeping the planet's orbit stable, or risk endangering the very existence of The Federation. I am aware of the consequences for the local population, Doctor, but simply rushing in to 'save the high priestess' will leave us open to a Klingon ambush with a 78.52% probability of outright destruction.
— Mr. Jaggers, Great Expectations
I realize this is a hard choice, Captain, but the needs of the many must outweigh the needs of the few." A character who will always think before acting, The Spock is an archetype that can be loosely summed up as the tendency to apply rules, reason and the greater good to all of his/her decisions. This character can exist by themselves, but more often, they will have a more emotional and humanistic counterpart to contrast their decisions. The main difference between the two archetypes is that while The McCoy will leap before looking, The Spock's solution to problems will have a balanced and well-thought out approach. The Spock's relationship with his crewmates/comrades is often tense, because this character type is willing and able to ruthlessly consider ethically troubling situations without batting an eye — especially situations where people might be ordered to die. While his counterpart The McCoy is interested in doing the right thing regardless of cost, The Spock is more interested in the end result. For him, everyone (including himself) is expendable and he has no problem treating people as such. The Spock maintains audience sympathy by being willing to Take a Third Option and also by being as ruthless about his own life as the lives of his crewmates, if not more so. Even better, he is utterly unflappable in the face of serious problems or danger; his friends know that no matter how terrifying or hopeless things get, he will never lose his cool and will not stop working on a solution to save everyone. When put in a Power Trio with The Kirk and The McCoy, he becomes the superego in Id, Superego and Ego. The Spock will at times become a Tin Man, though this varies with the writing, and will often have No Sense of Humor. When he has emotion, he may sometimes express it with a Fascinating Eyebrow and nothing more. Since Smart People Play Chess, if The Spock plays a game, it will invariably be a variant of chess. Closely related to The Stoic, Agent Scully, Emotionless Girl, and Little Miss Snarker. Often becomes a Straw Vulcan, but occasionally ends up on the winning side of Emotions vs. Stoicism. Probably sides with the Enlightenment in Romanticism Versus Enlightenment. Well Intentioned Extremists often come across similarly when they believe they're working for the greater good. See also Spock Speak. This character type is Shoot the Dog personified. Named (obviously) for Spock from Star Trek. Compare with their eternal opposite, The McCoy.

Anime and Manga
- "D" from Dual! Parallel Trouble Adventure.
- Hoshino Ruri from Martian Successor Nadesico is both The Spock and a Little Miss Snarker.
- Nagato Yuki from Haruhi Suzumiya.
- Keith Anyan from Toward the Terra.
- Lumiere from Kiddy Grade.
- All Contractors in Darker Than Black are said to be like this; part of their condition is that they always act rationally and with their own best interests in mind, dismissing emotional attachments. Throughout the series several counter-examples are shown, to the degree that whether the statement is actually true is up for discussion.
- Inspector Lunge from Monster.
- He acts like The Spock, but it should be noted that, mainly due to his own Pride, he disregards mounting evidence of Johan's existence until it becomes overwhelming. A true Spock would have impartially re-evaluated evidence and circumstances as they changed and based his judgements purely on logic. Also, his big fight with Roberto shows that he does have an emotional Berserk Button, and while his handcuffing himself to Tenma after being badly wounded is admirably Badass, it could hardly be called a rational decision.
- Exedore/Exsedol from the Macross and Robotech universes, though he has his emotional moments, too.
- Fate from Mahou Sensei Negima! is a villainous version of this.
- Paul von Oberstein from Legend of Galactic Heroes is a good example of this trope.
- L from Death Note is a surprisingly good one, too. There's a minor deviation in that he sometimes informs people of his emotions, even though he doesn't display them unless the situation's truly dire. Near also qualifies. Mello? Not at all...
- Ulquiorra from Bleach appears to be a villainous example of this trope- while his comrades generally act like children, he openly describes himself as an emotionless tool for Aizen to use as he pleases. The closest he ever comes to showing emotion are several cases where his eyes slightly widen and a single instance where he raises his voice.
- Wilhelmina in Shakugan no Shana. There was even an episode called "Heartless Wilhelmina".
- Sai from Naruto. He was raised in ROOT, which means he has no emotions whatsoever. Although he gets better at understanding them later when he joins team 7.
- Tobirama Senju, aka the 2nd Hokage, is also this, especially compared to his older brother the 1st. He always advocates taking the most logical action in the face of a conflict, even if said action is callous and/or ethically questionable. Whether the story is sympathetic to this varies and can be anywhere between Jerkass Has a Point and Unwitting Instigator of Doom.
- Kyoya from Ouran High School Host Club. He deliberately crafts a hardened, purely logical exterior, and gets pretty annoyed/confused when people (Tamaki, Haruhi) see through it. He's the one really running the club and making all the real decisions - slightly subverted, though, in that nobody fights him on his decisions since he never has to make life or death choices.
- C. C. from Code Geass is a particularly snarky variant, at least while the cold side of her Sugar and Ice Personality is the one being shown. Far from being emotionless, she has very strong feelings, she is just able to keep them under control most of the time.
- Natarle in the Gundam Seed Power Trio.
- She would fire missiles at an ally Gundam, knowing its armor would survive the hit, for the chance of hitting the enemy.
- Rossiu of Tengen Toppa Gurren Lagann, whose otherwise reasonable actions in an unreasonable setting makes him Wrong Genre Savvy and thus totally obsolete.
- Rei Ayanami and Ritsuko Akagi of Neon Genesis Evangelion.
- Seto Kaiba from Yu-Gi-Oh!.
- Piccolo of Dragon Ball Z…sometimes. He first appears as a raving, cackling lunatic hell-bent on killing Goku (justified, as he has all his father's memories, and is only a few years old.) Then he mellows, is shown meditating in a lotus position, becomes an Anti-Hero, and voila. Also, he's arguably the most intelligent character on the show. Sometimes, though, he gets angry. Like if Gohan gets hurt. Then he goes from being The Spock to a Papa Wolf.
- Fuu Hououji of Magic Knight Rayearth is an unusual example. She is much more calm, observant, and thoughtful than Hikaru and Umi , but she also applies her logic to a strong sense of compassion and attempts to comfort her friends.
- Brainiac 5 of DC's Legion of Super-Heroes.
- Metron of the New Gods who was explicitly based on Spock.
- The Vision of Marvel's The Avengers. No wonder, he's a robot after all. Partially averted on times, Depending on the Writer: he may show human emotions to a high or low extension, or lack them completely.
- Dr. Manhattan of Watchmen, who is referred to as "goddamn Mr Spock there" by a minor character at a cocktail party.
- Taken to epic levels in Final Crisis: Superman Beyond with the Composite Character Captain Allen Adam, A.K.A. the Quantum Superman of Earth 4, who is a meshing of the Good Doctor with the original Captain Atom. Even when on heavy drugs to keep his quantum senses in check he's capable of feats of extreme mental prowess, and after his drugs fade off he attains a state of nigh-omniscience and arranges the activation of the Cosmic Armor that saves all of reality from an Eldritch Abomination that eats stories. Only The Spock can stay calm and babble about the organic nature of The Multiverse while the Ultimate Evil emerges.
- Prowl, more so in the comic (which is why it's here). IDW's take deconstructs this- Prowl's lack of empathy and I Did What I Had to Do attitude alienate him from the rest of the Autobots, even those who were previously his friends. During Transformers: Robots in Disguise and Transformers: Combiner Wars, it's show that his "logical" behavior isn't even that logical- he's motivated as much by a desire for revenge and lingering mental instability over his torture by the Decepticons and being made a part of Devastator.
- Shockwave, though he's a villain. Typically it's considered his strength, as he can remain emotionally detached and not get distracted like Megatron or Starscream are prone to doing. Subverted in IDW's Spotlight: Shockwave, when he's unable to figure out a logical reason for why the Dinobots attacked him and begins losing the fight, only to realize that their reason is illogical: they're after revenge and he's only able to turn the fight around by deliberately activating an illogical rage mode.
- Skalman in Bamse is almost an example, but he is usually even less likely to suggest a course of action that seems unethical - in fact, it is sometimes shown that being logical and thinking things through allows him to do the opposite.
- James-Michael of Omega The Unknown, due to his being raised by robot protectors.
- The Treen of Dan Dare are completely emotionless and driven by logic. Sondar, a good Treen, is capable of feeling emotion, but still approaches problems logically.
- While he's the self-styled leader of the Fantastic Four, Reed Richards is most comfortable as the thinker of the group. If anyone is The Kirk it's his wife Sue.
- Advice and Trust: Rei always tries to be logical and rational. Her mindset is: logic makes things clearer and simpler. And thanks to that mindset she starts out to break Gendo's control upon her. She was being ordered to take a bunch of pills whose purpose was turning her into an emotionless doll. Asuka and Shinji warned her that her medication regimen was hazardous to her health. She researched, and her research proved Asuka was right. Ergo, Rei stopped taking her medication.
- Harry Potter and the Methods of Rationality: Harry is too young and emotional to be The Spock, but he sees it as an ideal, and always tries to ignore his emotions and make decisions based on pure logic. Occasionally a bit of a deconstruction, as his "purely rational" decisions often come across as cold or even cruel, and may be leading him to become a dark lord. For Example, when he rationalizes that killing a unicorn to extend Quirrel's life is no worse than killing a cow to eat, even though his gut instinct tells him not to.
- Reservoir Dogs - Mr Pink is the most logical of all the crew, especially when he acts as the foil to Mr White. The first scene shows him refusing to throw in money to tip the waitress, giving his reason as to why. He is later distrustful of everyone, and disgusted that Mr White gave Mr Orange his real name and hometown, considering anybody, even the dying Mr Orange, could be the rat. Not only is he right about everything, but he is the only character to survive the film. Subverted in that Mr. Pink is anything but cool—he's both logical and wildly neurotic.
- Dr. Egon Spengler from Ghostbusters (1984). In the [Ghostbusters II sequel]], he says that his parents did not believe in toys and he seems to be nigh-immune to the mood slime which makes the two most "positive" Ghostbusters try to kill each other. In the commentary for the original film, Harold Ramis notes that he deliberately played Egon as a Spock-like character. He also notes that there is only one scene where he actually shows emotion, when Walter Peck tries to have the Ghostbusters arrested for an explosion that he caused himself.
- For the record, Egon was affected by the mood slime in the novelization and script of the movie. He was, however, the first to overcome its effects.
- Juror #4 (the stockbroker with wire rim glasses) from 12 Angry Men. He's one of the longest holdouts against Juror #8, but unlike #10, who is motivated by bigotry, or #3, who is projecting his family issues onto the case, #4 is simply not convinced by the circumstantial logic that #8 offers as reasonable doubt and sticks to the defendant's inability to remember the movies he claimed to see. He only changes his vote when #8 quizzes him on the last double-feature he saw and he's unable to remember basic details himself, proving that the defendant's claim is plausible after all.
- Sunshine. When the crew out to save the sun (and the world) are down to five members and their oxygen supply is cut, they realize they only have enough oxygen for four people to make a return trip. Michelle Yeoh doesn't bat an eyelid in suggesting they murder one of their own (whom happened to be already wracked with guilt for a mistake that led them into this predicament in the first place) instead of all five of them dying from lack of oxygen, and it didn't take much convincing for two other crew members to accept the idea.
- The Avengers: Iron Man fits The Kirk, and Captain America fits The McCoy. Black Widow being the most calculating and logical of the group would fit The Spock.
- Although in terms of Iron Man and Captain America alone, these two show a different dynamic with Steve being The Spock. He is the tactician of the team and less of an ideological hero than he was in his own movie, while Tony is clearly dismayed at how calm he is following Coulson's death and has a moment where he wins Bruce over through sheer compassion.
- Ivan of The Brothers Karamazov.
- Elinor Dashwood, the protagonist of Sense and Sensibility, in contrast to her sister Marianne. Possibly the Trope Maker, considering this is one of the first known intentional uses of it (Austen intended the sisters' Emotions Versus Stoicism to be a metaphor for Romanticism Versus Enlightenment). Also one of the few examples where The Spock is right, and The McCoy has to learn to be more reserved rather than the other way around.
- Death in the Discworld series. Is attempting to understand the human race, but is finding it...difficult. At times he seems to know a bit more about human nature than he lets on though, so maybe it's just an act.
- Voort "Piggy" saBinring from Wraith Squadron. He's a Pig Man from a species more known for violent aggression and stupidity, but brain tampering made him into a Genius Bruiser, Good with Numbers and tending to be logical and calm. We see a bestial side exactly once, and it takes getting gut-shot to bring it out. Sort of similar to Vulcans, who practice emotional suppression precisely because their emotions are so violent and difficult to control compared with other species.
- The Mentats in the Dune series.
- Michael Valentine Smith from Robert A. Heinlein's Stranger in a Strange Land. He is capable of feeling overwhelming emotion, but when he does, he simply slips into a coma until he's found a way to logically respond to the situation. As a human raised on Mars, it takes him quite a while to understand laughter, grief, fear and loss - his only emotions at the start of the book are curiosity and love.
- C.S Forester is fond of this. The captains in The Good Shepherd and The Captain from Connecticut were very extreme Spocks. Horatio Hornblower was a slightly more mild version but still something of a Spock.
- Asher in Someone Else's War.
- The Dresden Files
- Mab to the extreme, in contrast with her sister Titania, who is The McCoy. Mab is utterly ruthless and pragmatic in pursuit of her goals of protecting reality from the Outsiders.
- However, Mab is also The McCoy to her mother, Mother Winter, the ultimate pragmatist. Mother Winter calls Mab a softy because Mab won't kill Mab's own daughter Maeve when Maeve has become a traitor. Mab has just enough emotion and humanity left to find herself incapable of acting as she knows she should.
- Arthur Conan Doyle's Sherlock Holmes is the Ur-Example. Mycroft could be seen as this, too.
Live Action TV
- Spock from Star Trek: The Original Series. Gene Roddenberry went on record saying that Spock is an idealized version of himself, as he'd always bemoaned his own passionate and hot-tempered nature.
Spock: I realize this is a hard choice, Captain, but the needs of the many must outweigh the needs of the few.
- Like The Kirk and The McCoy, there's some Generation Xerox between the different series. Consider:
- Data from Star Trek: The Next Generation. Subverted, though, in that Data is actually aspiring to become more human, and makes significant strides toward that throughout the show and its films. Still, as Spock himself put it:
Spock: Fascinating. You have an efficient intellect, superior physical skills, no emotional impediments... there are Vulcans who aspire all their lives to achieve what you've been given, by design.
- Dax originally had shades of this in Star Trek: Deep Space Nine (this is lampshaded in a time travel episode where she unknowingly parrots Spock's statistical readings), but grew organically into a party girl and textbook case of Immortal Immaturity. The acerbic security chief, Odo, is much closer to this.
- Seven of Nine from Star Trek: Voyager, though she tries to overcome this in later parts of the show.
- Data from Star Trek: The Next Generation. Subverted, though, in that Data is actually aspiring to become more human, and makes significant strides toward that throughout the show and its films. Still, as Spock himself put it:
- Sherlock: Sherlock, Moriarty, Magnussen and Mycroft are this, definitely. The only way to get Sherlock pissed is to hurt Mrs. Hudson or threaten John's life, though.
- Cristina Yang from Grey's Anatomy.
- Strangely enough, for all the jokes of his lack of intelligence, this is usually the role Jayne Cobb plays in Firefly. Ruthlessly pragmatic, Jayne will always be the first one to suggest that the smartest course of action when in a bind would be to betray this person or abandon that cause. Rarely is his logic on these matters ever called into question, but no one else is willing to be that cut-throat.
- Temperance "Bones" Brennan from Bones. This becomes funny given that another character called "Bones" from Star Trek is the original McCoy. Also, Zack Addy.
- Teal'c of Stargate SG-1 is sometimes The Spock, in that he has the same unflappability and (usually) rational thinking, though he's more The Stoic than a person who actually doesn't experience emotion (several episodes demonstrate he experiences emotions quite intensely, especially in relation to his family and in relation to his cause of freeing his people).
- Ficus in Quark is a parody of The Spock taken to extremes. He's a sentient plant and has absolutely no emotions, taking everything logically and speaking only in Spock Speak.
- Aeryn Sun of Farscape is a minor tactical genius and never loses her cool...perhaps to her detriment, as the path of her relationship with Crichton is rocky and convoluted. She becomes more The Kirk as she goes along.
- Sikozu and, after his Heel–Face Turn, Scorpius are perhaps the purest Spock members of the crew,having a tendency to be coldly pragmatic about problems.
- Rygel is a slight subversion, as he has a tendency to on occasion claim his actions are for the best of the crew as a whole, but more often than not he's just being a greedy self-interested Jerk Ass. He has his moments, however.
- Sheldon in The Big Bang Theory. Lampshaded, as Sheldon considers his circle of friends one doctor short of a landing party, and has proclaimed himself the Spock. Sheldon might not be a full-fledged example of this trope, though. He's too self-centered to be detached from the situation, so to speak - but Leonard's mother, Beverly, fits this trope very well.
- Freddie on iCarly, opposite to Carly (The Kirk) and Sam (The McCoy).
- Moze on Ned's Declassified School Survival Guide, with Cookie as The McCoy and Ned as The Kirk.
- Doctor Larry Fleinhart from NUMB3RS. Surprisingly, Doctor Charlie Epps doesn't qualify, as he emotes just fine. More surprising as Larry is the Romantic one and Charlie is the Enlightened one.
- Castiel the doubting angel from Supernatural.
- Rupert Giles in Buffy the Vampire Slayer. Subverted, as he is often flustered or baffled, but forces himself to adhere to the cold-headed British persona he was raised to believe was most proper for any occasion.
- House in House.
- Cameron in Terminator: The Sarah Connor Chronicles. While she can emulate emotion, she usually goes the most coldly pragmatic route.
- Jor-El in Smallville. He often cooks up options for Clark to beat the bad guy that involve sacrificing his friends. He is however, prone to getting royally pissed at Clark for refusing to listen to him.
- Dr. Moira Isles from Rizzoli & Isles.
Rizzoli: You'd tell me if you were a cyborg, right?
- Hauser in Alcatraz is a rather unpleasant version of this trope.
- Jack Harkness from Torchwood. Interesting, in that he was The Kirk to the Doctor, originally.
- Clayton Webb, but even more so Sturgis Turner, fills this role in JAG.
- Scandal: Olivia.
- Kerr Avon from Blake's 7 is a rather cynical version.
- Robert McCall, The Equalizer, is very much this but has tempered it some on his own by choosing to stick to ideals he had put away for the greater good when he was part of The Agency. He always prefers logic, rationalism, and hard facts to intuition, and never lets his emotions rule instead of his head, always calculating and manipulating the odds, and willing to pay the cost himself to save someone's life.
- Also, Control from the same series, the only person in the series to out-Spock McCall and to whom McCall could look like a McCoy next to.
- Kane is this on The 100, always putting the rules of the Ark and The Needs of the Many ahead of everything else. However, he seems to recognize that sometimes a more warm-hearted approach is needed; he just can't provide it himself, and so prefers acting as second-in-command rather than The Leader.
- Lexa is another example. She believes that love (and emotions in general) are a weakness, and is ruthless about sacrificing anyone, even herself or those close to her, if she believes it's what's best for her people.
- Linus often performs this function for Charlie Brown in Peanuts. Likewise Schroeder to Lucy (and occasionally Charlie).
- Alchemical Exalted have a trait called "Clarity" that tracks how much of this personality they accumulate; as they grow in Clarity, they become increasingly focused on pragmatic and efficient solutions and will place lower priority on compassionate activity, at the cost of becoming increasingly less emotional and having difficulty relating to other people (they also have some Charms that can harness Clarity to grant increased cognitive ability). Clarity is reduced by prolonged meaningful interaction with normal human beings (or, in the case of some Alchemicals, immersion in memories from their past lives).
- Warhammer 40,000
- Among the Primarchs, there was Ferrus Manus on the Imperial side and Perturabo among the traitors. Both tended to be the most dispassionate and calculating Primarchs, and their Legions followed suit - although Perturabo's claim is a little weakened by his towering resentment and susceptibility to brief spasms of uncontrollable fury.
- Adeptus Mechanicus supporting character tends to be this to whatever Inquisitor, Space Marine or Imperial Guard protagonist they follow around, especially if they have had the cybernetic surgical procedures of Clear Thoughts, excising the parts of their brains capable of emotions.
- A rare main character example: Brutus from Shakespeare's Julius Caesar, with either Cassius or Antony as The McCoy. A quiet, (literally) stoic, cool-headed intellectual who is a friend of Caesar's but is willing to do him in since, to quote the Trope Namer, the needs of the many outweigh the needs of the few. ("Not that I loved Caesar less, but that I loved Rome more!")
- In Shakespeare's Troilus and Cressida: Ulysses on the Greek side, with Agamemnon as The Kirk and Ajax as a fairly thickheaded variation on The McCoy. On the Trojan side, Hector fills this role, to Priam as Kirk and Troilus as The McCoy
- In Romeo and Juliet, Benvolio is this to Romeo, with Mercutio as The McCoy.
- Kopaka, the resident Stoic in BIONICLE.
- Transformers: Almost all versions of Shockwave are what you get when this type of character is a villain. Cold, calculating, and unflinching. The original comic version even decided to overthrow Megatron, because it was the logical thing to do. And later on, he handed back power to Megatron, again because it was perfectly logical for him to do so. Best encapsulated by this quote from another Shockwave:
Shockwave: Ultimately, I serve only one master: Pure logic.
- ADA in Zone of the Enders. Why waste time and put yourself at risk saving innocent civilians when you could just hurry up and get the war-changing mech Jehuty to its destination?
- Mass Effect 2:
- Mordin Solus, though Hidden Depths reveal that he's way more compassionate than he lets on and feels incredible regret for his Well-Intentioned Extremist moment (though he feels it's still the right choice).
- The Ruthless background Shepard also qualifies, doing whatever it takes to get the job done, no matter how horrific, and usually in the middle of the action himself—the military's go-to guy for the most vital and most morally compromising missions. The Renegade morality path also comes off as this in all the major decisions and in many of the conversations (with the rest of the time consisting of being a hardass, and in some instances in the first game, a bit of a xenophobe as well)
- Squall of Final Fantasy VIII is a rare main character version. Raised as a mercenary, he's cynical about how the world works and tries to act solely according to duty rather than emotion. For the first portion of the game he seems like a lone Spock in a team of McCoys, but much of his Character Development is him learning how to healthily feel and express his emotions rather than acting like an automaton until he blows a gasket over, say, the execution of someone he knew from childhood.
- Stern, the Material of Wisdom in the Magical Girl Lyrical Nanoha A's Portable games. Funnily enough, this made her the kindest one amongst the Materials and the first one to make a Heel–Face Turn away from their Omnicidal Maniac side since she came to the logical conclusion that mindlessly destroying everything is stupid.
- Jade Curtiss of Tales of the Abyss, despite his Stepford Smiler outward persona, fits this trope when it comes down to actual decision-making. It's a Crowning Moment of Heartwarming the one time that he does admit he'd rather not do the most coldly logical thing, which would be to ask Luke to sacrifice himself rather than Asch.
- Jusqua of Final Fantasy: The 4 Heroes of Light thinks that he's this. When Horne is petrified, he doesn't go with Brandt and Yunita because they can find a way to lift the curse. Later, he faces up to the fact that he was actually being immature by snarking at them when he himself was unwilling to try anything he thought he'd fail at.
- Dangan Ronpa has Kirigiri, who is coldly aloof, calculating, and emotionless. Celes is one as well, what with her saying they should abandon all attachment to the outside world and just accept their fate living in Hope's Peak though ultimately subverted when it's revealed that she's so desperate to get out that she orchestrates a double murder. Togami is a milder, crueler version.
- Super Dangan Ronpa 2 introduces Izuru Kamukura, who makes all of the above look hotheaded. He used to be a perfectly ordinary guy, until he accepted to subject himself to an operation in order to become as talented as the other Ultimates. The end result: he acquired every talent, but his emotions are completely gone and he has no drive other than acquire other talents.
- The Orpheans in Xenoblade Chronicles X are an entire race of these. While they can feel emotions, they mostly keep them in check in favor of finding the most efficient solution to their problems through pure logic.
- Maurice Chausson always puts the needs of NLA above the needs of any individual person even to the point of leaving his own son on Earth. The only reason he shows Team Elma preferential treatment is that they're just so damn good at their jobs that losing any of them would be equivalent to losing 20 other BLADEs.
- Vaarsuvius from The Order of the Stick tries to be this in order to become more effective and overcome a great obstacle, but seeing as how the elf is anything but emotionless and is in fact haunted by the memory of a great failure, the result is disastrous.
- Zombie/Narrator/.../whatever you want to call him plays this pretty straight in Hanna Is Not a Boy's Name
- Quinn-Tain in Harkovast bases his decision only on what he thinks is necessary to win the war. Emotional concerns are always secondary.
- Mr. Raven in El Goonish Shive.
- The AI Delta from Red vs. Blue is logic personified. Literally. Ironically, Delta is probably the most humane of the various Freelancer AIs, despite his noticeably incomplete understanding of human nature.
- In the ''Global Guardians, Achilles is the The Spock, and is also the team leader. Guardsman is The Kirk, while Arachne and Ultra-Man are The McCoy.
- Lady Ink from The Book of Stories OCT. Of course, she is a personification of order and structure, so it makes sense.
- Flame Warriors: Android, who is emotionless and only notes illogic in other flame warriors' arguments.
- Star Trek: The Animated Series has Spock in this role, of course.
- Wind Whistler of My Little Pony 'n Friends.
- In My Little Pony: Friendship Is Magic, Twilight Sparkle takes this role in the first two episodes, not caring about "pointless" things like friends or fun. She ends up coming around at the end of the second episode, and the rest of the season documents her learning about just how kick ass friends are. She occasionally lapses into this when academic subjects are mentioned, especially magic. She has a very logical, scientific view of the world and though her excellent education means that she's often right, it does leave her rather inflexible. Her tendency to dismiss information that she finds illogical in particular has been called on more than once.
- Celestia, the Big Good of the series, more than once put the main cast (whom she is said to tresure) in a dangerous position with a gentle smile, sometimes without telling them so. Of course, given her position and age it is somewhat expected...
- Big Brain from an episode of Adventures in Care-a-Lot.
- Marsala from Exo Squad, even though others of his species are generally much more emotional than he is.
- Sokka from Avatar: The Last Airbender, so much so that he comes into conflict with the rest of the group.
- Braniac 5 from the Legion of Super-Heroes usually fits this trope. As does the Martian Manhunter.
- Dr. Egon Spengler continues to be as Spock-like in The Real Ghostbusters cartoon as he was in the films, going so far as to remind a space station full of Star Fleet Expies of an old colleague.
Egon: (after delivering a stream of Techno Babble) Fascinating.McTavish: Are you sure you've never served as a science officer?
- Dr. Herman Kahn. His works in the 1950s on nuclear war examine the aftermath in extremely dry terms. He was considered a sort of monster by some to actually argue that, while extremely horrible, a nuclear holocaust would not be the end of humanity.
- Within the Power Trio of the Allied leadership of World War II, Josef Stalin played the Spock to FDR's Kirk and Winston Churchill's McCoy. When you're a dictator who sees himself as just doing what it takes to ensure your country's survival (occasionally even half-admitting being Necessarily Evil), it sort of comes with the territory.
- Admiral Raymond Spruance, especially when compared to his Red Oni Admiral Halsey's tendency to pull the Leeroy Jenkins.
- INTPs on the Myers-Briggs scale are stereotypically like this. INTJs, too. "Does it work?"
- Has a pretty firm footing in alexithymia.
- By his own admission, Ehud Barak, one-time Prime Minister and repeat Defense Minister of Israel, and one of the best generals in the IDF's history. He and everyone around him quite frankly states that Barak's mind is like a steel trap: remorselessly methodical and logical, remembering everything, and expecting everyone to be just as logical as he. Barak, however, does have the humanity to admit that this is something of a double-edged sword: his logical method blinded him to the emotions of others, particularly the Palestinian and Syrian diplomats he tried to negotiate with at Camp David in 2000. This insensitivity—again by his own admission—probably cost him the deal of the century.
- The leopard, in comparison to other big cats. Lacking the teamwork of lions or the raw strength of tigers, leopards rely on a combination of cunning, versatility, and calculated risk to survive. They are opportunistic hunters that carefully judge their prey before attacking, and actively avoid confrontation with stronger competing species.
